Hello:

I have this problem in openSUSE Leap 42.2. dmesg if full with the following message:

[12458.196131] Leftover inexact backtrace: ------------------

This is repeated endless times.

I googled and found that other have this bug, but I couldn't find a fix.

The computer is working OK as far as I can say.

Is there anything I should do with this or can I ignore this message?

I have two other questions related:

1. This error message is shown repeatedly in a working virtual terminal window (vt 1-6). If I login to a vt the message interrupts my typing and makes impossible to work in the terminal. How can I fix this?

2. I tried to have a look at log messages and discovered I don't have /var/log/messages file? Where is the log file, I mean a simple text file I can read with any simple text viewer from any operating system.

Thanks,

Istvan

There is no /var/log/messages anymore . It's been replaced by journaling, which you can access by using journalctl .

Are you saying that there is no way to set the system to produce simple text log files? How can I read the logs then if I mount openSUSE partition in another OS which doesn't have the specific tool?

if you want /var/log/messages to exist, you must install rsyslog. the install process will switch you to using syslog *and* journald, which you can limit by editing /etc/systemd/journald.conf and redirecting output.

Thank you Patrick, I will look into this.

What about the error messages spitting my terminal screen?

I have seen something about outputting kernel msgs or system msgs to a tty and have mine directed to tty10, but I don't recall the procedure. maybe google it. ps: a kernel oops will still output everywhere. -- (paka)Patrick Shanahan Plainfield, Indiana, USA @ptilopteri http://en.opensuse.org openSUSE Community Member facebook/ptilopteri Registered Linux User #207535 @ http://linuxcounter.net Photos: http://wahoo.no-ip.org/piwigo paka @ IRCnet freenode -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
